Honey: The Sweet Secret to Evolution (Rebroadcast)

The Hazda people really, really love honey. The hunter-gatherer tribe from Tanzania loves it so much, that the men will risk death for it - climbing 30-foot high trees, smoking bees out of their hives, then pulling out chunks of honeycomb with their bare hands. UNLV anthropologist Alyssa Crittenden worked with them for eight years - and found surprising news about how important honey is to our own diet, and how it even shaped our evolution as human beings. Originally aired 3/5/12.
